432 Park Avenue is a residential skyscraper at 57th Street and Park Avenue in Midtown Manhattan in New York City, New York, U.S. The 1,396-foot-tall (425.5 m) tower was developed by CIM Group and Harry B. Macklowe and designed by Rafael Viñoly. A part of Billionaires' Row, 432 Park Avenue has some of the most expensive residences in the city, with the median unit selling for tens of millions of dollars. At the time of its completion in 2015, 432 Park Avenue was the third-tallest building in the United States and the tallest residential building in the world. As of 2023, it is the sixth-tallest building in the United States, the fifth-tallest building in New York City, and the third-tallest residential building in the world.

432 Park Avenue has 84 numbered stories and a mezzanine above ground. The tower's exterior is a lattice of poured-in-place concrete made from white Portland cement. The tower is segmented into 12-story blocks separated by open double-story mechanical spaces that allow wind gusts to pass through the building. It features 125 condominiums and amenities such as a private restaurant for residents. The skyscraper has received mixed reviews from both professionals and the public, with commentary about both its slenderness and its symbolism as a residence for the ultra-wealthy.

432 Park Avenue is located on the site of the former Drake Hotel, which was sold to Macklowe in 2006. The project faced delays for five years because of lack of financing as well as difficulties in acquiring the properties on the site. Construction plans were approved for 432 Park Avenue in 2011 and excavations began the next year. Sales within 432 Park Avenue were launched in 2013; the building topped out during October 2014 and was officially completed in 2015. After the building's completion, residents complained of mechanical and structural problems, leading to multiple lawsuits in the 2020s.
